The Village of Fox Lake operates two separate water systems – the South System, and the North System consisting of wells 2, 3, 4 and 5, a 250,000 gallon elevated storage tank, and two 500,000 gallon elevated storage tanks. The South System has good redundancy and sufficient storage at pressure for normal Village supply as well as sufficient water for fire fighting.

The North System has two wells and a 500,000 gallon ground storage tank, with pressure on the system maintained by variable speed pumping. While the pumping station is equipped with a standby generator to provide water pressure during a power outage, activation of the generator could not be made quickly enough to prevent system pressure from falling to unacceptable levels. The low pressure events require boil order to be issued until such time that the safety of the water could be verified.

The Village determined that an elevated storage tank should be constructed on the North System, which would store pressure for both normal use as well as fire flow, and provide pressure during a power outage. A 500,000 gallon elevated tank was selected for construction at the Village’s Tall Oaks facility, adjacent to the existing ground storage tank and booster station. Once the new elevated storage tank is on-line, the existing booster station will be taken out of service in order to perform a needed refurbishment, which is included in the project.
